The Nuclear Nonproliferation Treaty

  • Page ID

    The distribution of power is when power, influence or authority is distributed, spread around or apportioned.



    Ratified in 1968 by the United States, United Kingdom and Soviet Union, the nuclear Nonproliferation Treaty (NPT), was designed to place controls over the development, spread and use of technology that could be used to create nuclear weapons. Countries already possessing nuclear weapons could not give/sell these weapons to other countries not possessing these types of weapons and were banned from sharing the technological information necessary for the manufacture of such weapons. Countries without nuclear weapons capabilities signed a pact agreeing not to receive or manufacture these types of weapons. Since that time, the International Atomic Energy Agency (IAEA) -- the nuclear watchdog of the United Nations -- has been in charge of enforcing nonproliferation among the 188 countries that have signed the pact.

    In May 2005, a conference will take place in New York City with an agenda focused on revising the treaty to address issues that have arisen since the last review meeting in May 2000. Since that time there have been a number of key events that have tested the treaty and various new threats that the treaty would need to address.
